Background technology
As everyone knows, the RFID label is made of IC chip, antenna, substrate, and carries out the device that specified data is received and dispatched with outside rfid interrogator.RFID label and rfid interrogator carry out non-contacting data transmit-receive, height according to the employing frequency, coupling scheme between the two can be divided into inductive coupling (Inductive Coupling), electromagnetic field backscattering coupling (Back ScatteringCoupling), surface acoustic wave coupling (Surface Acoustic Wave Coupling) etc., according to the difference of the electromagnetic wave that is utilized, can be divided into full duplex, half-duplex again to data transmission receive mode.Rfid interrogator reads or writes the data that are stored in the RFID label by carrying out the transmission and the reception of wireless signal with the RFID label.
RFID label of the prior art, what its substrate material was selected for use is the rigid plastic that a kind of epoxy resin constitutes, and causes label can't stick on special stickup positions such as identifying object thing corner; Moreover, the antenna of label is copper (Cu) thin plate material, its stickup is attached on the substrate one side, that brings thus is limited as: parameters such as difficult length, angle, spacing, thickness by adjusting antenna realize the optimum matching between antenna impedance and the RFID chip impedance, RFID reader correct problem of identification label in decipherment distance so will occur.
The utility model content
The utility model purpose is to overcome the deficiencies in the prior art, a kind of flexible uhf band RFID label is provided, it adopts the good soft synthetic resin material label substrate of pliability, solves it and be difficult to stick together fixing problem on the position, corner of automatic identifying object thing; Use silver (Ag) material directly to be printed on the label substrate surface, and first, second antenna is set respectively at the substrate tow sides, and realize between the two electric connection by RFID IC chip, be convenient to realize the optimum impedance coupling between label antenna and the chip thus.
The utility model is achieved through the following technical solutions, a kind of flexible uhf band RFID label, comprise substrate, antenna, chip, described substrate is the soft resin body, described antenna is P.e.c. and comprises first antenna, second antenna, described first antenna and chip are covered in substrate front side jointly, first antenna comprises left and right sides two parts, chip is connected across on left and right sides two parts of first antenna, described second antenna is covered in the substrate reverse side, and second antenna extends to the left and right sides face of substrate and is connected with left and right sides two parts of first antenna.
Described first antenna is covered in substrate front side, and planar is repeatedly folding shape.
Described first antenna is covered in substrate front side and is ribbon.
Described second antenna is covered in the substrate reverse side and is ribbon.
Described soft resin body is the soft synthetic resin body.
Described P.e.c. is silver-colored material P.e.c..
Compared with prior art, the utility model label substrate itself selects the strong soft resin of pliability to replace the rigid plastic of original rigid material, thereby make flexible uhf band RFID label of the present utility model can stick on the positions such as corner of identifying object thing, and label is pasted easily; The antenna of RFID label does not re-use copper sheet, but adopt the P.e.c. of silver-colored material, the utility model has been printed respectively and can have been realized interconnective first, second antenna by RFID IC chip at the substrate tow sides, so be very easy to parameters such as length by adjusting antenna, angle, spacing, thickness and realize optimum matching between antenna impedance and the RFID chip impedance, but and effectively improved the discrimination of label.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is elaborated: present embodiment has provided detailed embodiment being to implement under the prerequisite with technical solutions of the utility model, but protection domain of the present utility model is not limited to following embodiment.
As Fig. 1 a, Fig. 1 b, shown in Figure 2, present embodiment RFID label 10 includes substrate 1, antenna, RFID IC chip 2, described substrate 1 is pliable and tough soft synthetic resin body, described antenna adopts silver-colored material printing and comprises first antenna 3, second antenna 5, described first antenna 3 and RFID IC chip 2 are printed in substrate 1 front jointly, first antenna 3 comprises left and right sides two parts, RFID IC chip 2 is connected on left and right sides two parts of first antenna and promptly is connected across on left and right sides two parts of first antenna, described second antenna 5 is printed in substrate 1 reverse side, and second antenna 5 extends the two sides 4 that are spread to substrate 1 and connects as one with left and right sides two parts of first antenna 1.Present embodiment RFID label 10 external packets are covered with slim transparent auxilliary material 6, and it is used to prevent that RFID IC chip 2 and antenna are damaged.
First antenna, 3 left and right sides two parts in substrate 1 front respectively along base plan extend to substrate about two sides 4,4, adapt to contour substrate and be around shape, and with the 5 one printings of second antenna, both are thus connected.
Shown in Fig. 1 a, Fig. 1 b, the rectangular RFID label substrate 1 in each angle is made (substituting by the strong soft synthetic resin material of pliability, described material it is also conceivable that selects to have plastic soft natural resin, or nonrigid plastic), can stick on the corner part of automatic identifying object thing 20 at an easy rate.And the RFID label of epoxy resin material was difficult to paste the position, corner of this type of object in the past.
Particularly, compare attached to the copper sheet above the substrate with prior art, the antenna circuit of present embodiment RFID label is silver-colored material P.e.c., it is that the silver that electric conductivity is very outstanding directly is printed on substrate 1 surface and forms, therefore the production process of label is very simple, not only enhance productivity, also strengthened the benefit of RFID label antenna, can increase the decipherment distance of rfid interrogator 40 in addition.
